Abstract
According to a method for measuring the inner diameter of a stepped hole, a standard bore dial indicator is utilized, a replaceable measuring head of the standard bore dial indicator is detached, a fixing hole in the position of the measuring head and an accessory specially provided with an indicator rod are utilized to carry out measurement, the special accessory comprises a support, a measuring rod, a pull rod, a pull rod sleeve, a fixing sleeve and a pressing plate, wherein the support is installed at the position where the replaceable measuring head of the standard bore dial indicator has been detached, the lower end of the measuring rod is movably connected with the support, the fixing sleeve and the pressing plate are fixedly installed at the middle-rear part of the indicator rod of the standard bore dial indicator after connected, the tail end of the pull rod sleeve is connected with the fixing sleeve and corresponds to the position of the measuring rod, the front end of the pull rod is movably connected with the measuring rod, the rear end of the pull rod is connected with the pull rod sleeve, the tail end of the pull rod can move front and back in the pull rod sleeve, and the replaceable measuring head which is detached from the standard bore dial indicator or additionally selected is connected with the upper end of the measuring rod. The method for measuring the inner diameter of the stepped hole is simple, easy to realize, and suitable for occasions where the standard bore dial indicator can only enter from a small hole end to measure the diameter of a large hole.
Description
Technical field
The present invention relates to a kind of stepped hole inner diameter measurement method, be applicable to the large bore dia of measurement from the small bore end of stepped hole stretches into.
Background technology
To some band step hole type parts, for guaranteeing precision and the Geometrical Tolerance Principle of processing metapore, need clamped one time to machine.Under part clamped condition, some hole (hole being processed as anti-boring) can not directly be measured with general vernier caliper and common dial bore gage, generally all adopt internal calliper to measure it, but the measuring accuracy of internal calliper is lower, for precision and the higher stepped hole of Geometrical Tolerance Principle, can not meet measurement requirement.
Summary of the invention
The object of the invention is, for above-mentioned defect, provide a kind of stepped hole inner diameter measurement method, to can measure general vernier caliper and the immeasurable step hole type parts of common inside diameter caliper easily and accurately.
The scheme that the present invention takes is:
Utilize the dial bore gage of standard, and by test probe replaceable dismounting on the dial bore gage of standard, utilize the fixed orifice at gauge head place and show after bar is installed special accessories and measure, described special accessories comprises bearing, measuring staff, pull bar, drag link sleeve, fixed cover and pressing plate, wherein bearing is arranged on the position after the dismounting of dial bore gage test probe replaceable, measuring staff lower end is movably connected on bearing, fixed cover is fixedly mounted on normal inner diameter dial gauge table bar postmedian after being connected with pressing plate, drag link sleeve tail end connects with fixed cover and is corresponding with measuring staff position, pull bar front end is flexibly connected with measuring staff, rear end is connected with drag link sleeve, pull bar tail end can move forward and backward in drag link sleeve, again the test probe replaceable of dismantling from the dial bore gage of standard or alternative is got is connected with measuring staff upper end.
Adopt the present invention to measure general vernier caliper and the immeasurable part of common dial bore gage, can also improve measuring accuracy.
Accompanying drawing explanation

Fig. 2 is the schematic diagram that the dial bore gage that uses in measuring method of the present invention inserts parts measurement in advance.
Fig. 3 is the dial bore gage measuring state schematic diagram using in measuring method of the present invention.
In figure: 1-dial bore gage, 2-slotted countersunk flat head screw, 3-pressing plate, 4-wing nut, 5-fixed cover, 6-drag link sleeve, 7-annular knurl flat head screw, 8-pull bar, 9-bearing, 10-screw, 11-straight pin, 12-spacer pin, 13-measuring staff, 14-test probe replaceable.
Embodiment
Below involutory accompanying drawing the present invention is described in detail:
As shown in the figure, measuring method of the present invention is to utilize the dial bore gage 1 of standard, and first by 14 dismountings of test probe replaceable on the dial bore gage of standard, utilize the fixed orifice at test probe replaceable 14 places to be installed and to be shown after bar is installed special accessories and measure, described annex comprises bearing 9, measuring staff 13, pull bar 8, drag link sleeve 6, fixed cover 5 and pressing plate 3, wherein bearing 9 is arranged on the position after dial bore gage 1 test probe replaceable 14 dismountings by screw 10, again measuring staff 13 lower ends are movably connected on bearing 9 by straight pin 11, bearing is provided with spacer pin simultaneously, prevent when measuring staff from producing offside, fixed cover 5 and pressing plate 3 are fixedly mounted on normal inner diameter dial gauge 1 table bar postmedian by slotted countersunk flat head screw 2, position is adjusted as the case may be, drag link sleeve 6 tail ends are connected with fixed cover 5 by wing nut 4, the installation site on pressing plate of drag link sleeve 6 is corresponding with measuring staff 13 positions, pull bar 8 front ends are by being flexibly connected with measuring staff 13 by straight pin 12, rear end is connected with drag link sleeve 6 by annular knurl flat head screw 7, pull bar 8 tail ends can move forward and backward in drag link sleeve 6, from dial bore gage 1 dismounting of standard or choose other satisfactory test probe replaceable 14 and be connected with measuring staff 13 upper ends, while measuring operation, first with outside micrometer, carry out zero, unclamp the annular knurl flat head screw 7 in annex, make pull bar and measuring staff in Fig. 2 state, so that table header stretches into macropore from small bore end, stretch into after macropore, pull pull bar 8, make measurer in Fig. 3 state, locking annular knurl flat head screw 7, part to be measured is measured, after unclamp again annular knurl flat head screw 7, make its head again after Fig. 2 state, from hole in piece part, take out measurer.
Adopt the present invention can be easily and accurately to being measured by general vernier caliper and the immeasurable part of common dial bore gage, and the inventive method be simple, realizes easily, is applicable to stretch into and measure large bore dia from small bore end.
